as-treated analysis

as-treated analysis

A method of measuring the outcomes of a clinical trial in which results are tabulated according to the actual treatments given to the patients rather than according to the treatments intended for the patients when they were assigned to their arm of the study. By contrast, an analysis based on an intended treatment assignment rather than actual treatment given is called an intention-to-treat analysis.

In the prespecified intent-to-treat analysis they were counted in the OMT group, whereas an as-treated analysis might well have shown statistically significant reductions in death and MI in the PCI group.

Using multiple office visits to identify ambulatory cases in an as-treated analysis would have required the introduction of immortal person time into the design, (30) hence those potential cases did not meet the study outcome definition.
